In addition, the left rail 22 and the right rail 24 are available for cargo management within the pickup truck bed and can be used for attaching tie down materials thereto. Exemplary tie down materials include bungee cords, ropes, straps, and clamps.

The left rail 22 includes a forward rail end 40 and a rearward rail end 41. The right rail 24 includes a forward rail end 42 and a rearward rail end 43. The left rail 22 and the right rail 24 are provided so that they extend along the left side wall 16 and the right side wall 18 of the pickup truck 14. The left rail 22 and the right rail 24 can be provided so that they are adjacent to the top surface 25 of the left side rail and the right side rail. It should be understood that materials such as foam or padding can be provided between the left side rail 22 and the left sidewall 16, and between the right side rail 24 and the right sidewall 18.

The left rail 22 and the right rail 24 can attach to the left sidewall 16 and the right sidewall 18 at the stake pockets provided in the left sidewall 14 and the right sidewall 18. Now referring to FIG. 3, a cutaway view taken along lines 3-3 of FIG. 2 shows how the left rail 22 can attach to the left sidewall 16. The left rail 22 (and the right rail 24) can be provided as an extrusion containing a sidewall mount opening 44 and a fairing mount opening 46. The sidewall mount opening 44 can be referred to as the first slot, and the fairing mount opening 46 can be referred to as the second slot. In general, the rails can be provided as an extrusion, such as an aluminum extrusion, where the first slot and the second slot extend the length of the rail. By providing the rails as extrusions, they can be cut to fit a desired vehicle size. A fastener 48 can be provided for attaching the left rail 22 to the left sidewall 16 by extending through the sidewall mount opening 44 and the stake pocket 50. In general, the fastener 48 can include a bolt 52, a washer 54, a spring 56, a bracket 58, and a nut 60. The washer 54 allows the bolt 52 to sit within the sidewall mount opening 44 and compress the rail bottom 62 against the bed rail track 64 of the sidewall. By tightening the nut 60, the fastener 48 compresses the left rail 22 onto the left sidewall 16. Similar connections can be provided at the remaining stake pocket locations at, for example, the left forward rail end 40, the left rearward rail end 41, the right forward rail end 42, and the right rearward rail end 43.

Now referring to FIGS. 1 and 3, end caps 65, 66, 67, and 68 can be provided on the rail ends 40, 41, 42, and 43 to provide a more finished appearance.
